Safety, built in.
Every machine in the range uses PEM/SPE membrane separation, so the user-facing stream is high-purity molecular hydrogen — never a flammable gas mixture. Multi-layer cut-offs handle the rest.
Separated gas streams
PEM/SPE separation produces hydrogen and oxygen in independent channels. The cannula delivers pure H₂ only — no flammable mixture at the user.
Multi-layer cut-offs
Automatic shut-down on over-temperature, over-pressure or low water level. The unit fails safe by default.
Clean water cycle
Distilled or deionised water in the internal reservoir. Simple top-up and full change schedule documented in the manual.
Studied at this dose
The published safety literature on inhaled molecular hydrogen at consumer inhaler concentrations has not identified significant adverse effects in healthy adults. See the evidence library for references.
When to consult a clinician first
Hydrogen Machines products are general wellness devices, not medical devices. Speak to a qualified clinician before starting hydrogen inhalation or hydrogen bathing if you are pregnant or breastfeeding, are under 18, have a serious cardiovascular, respiratory or neurological condition, use supplemental oxygen, are in active cancer treatment, or take medication where oxidative stress plays a defined clinical role.
